Reaction Conditions:

with copper(II) choride dihydrate;sodium carbonate in methanol at 25; for 0.25 h;Green chemistry;

Steps:

2. General procedure for homocoupling reactions of arylboronic acids
General procedure: Arylboronic acid (0.3 mmol), CuCl2·2H2O (2.5 mg, 5 mol%), Na2CO3 (10 mol%),methanol (1 mL) were added to a vial. The reaction mixture was stirred at 25 °C inthe air for 5-15 min and was monitored by TLC. Then the reaction was quenched withtwo drops of H2O, diluted with 2 mL of ethyl acetate, and filtered over a pad ofMgSO4 and silica. The pad was rinsed with additional ethyl acetate, and the solutionwas concentrated in vacuum. The crude material was loaded onto a silica gel columnand purified by flash chromatography.
